“For many, headphones are a true workout essential. We have designed the CX Sport to deliver everything athletes need to get the most out of their workout session — great sound, secure fit and a robust but lightweight design,” Marcel Salzmann, Sennheiser product manager, said in a statement. To that end, the CX Sport headphones are both sweat- and-splash resistant, so you don’t need to worry about going for a run in the rain.

Fit is everything when it comes to in-ears, so Sennheiser has included four sizes of ergonomic ear adapters to make sure that not only do the CX Sport fit, but remain comfortable and sound great as well. The headphones include a cable that is meant to run either behind your head or in front of you, but you don’t want this to aid in pulling them out of your ears, so an included cable organizer helps you keep the cable at the perfect length, while an optional clip will secure them to your shirt.

Sennheiser’s CX Sport headphones feature Bluetooth 4.2 and aptX for the clearest sound possible over Bluetooth, with Qualcomm aptX low latency to keep everything in sync when you’re watching a video. The headphones feature multi-connection capability, allowing them to stay connected to two devices at once, while the handy three-button remote lets you manage volume, playback, and calls.

When it comes to battery life, Sennheiser claims up to six hours of playback time on a single charge, though factors like overall volume will impact this number. A short 10-minute charge will get you another hour of playback time, and the headphones can be fully charged in around 1.5 hours.
